remove Eulerian dycore

Resolves #1170 - Remove Eulerian dycore from cam_development

Resolves #1148 - Update fire_emissions_factors in hist_trop_strat_vbsfire_cam6 usecase
. Note that this only changes answers for compset FCfireHIST which is not tested in the aux_cam group.

Resolves #1237 - Remove Eulerian dycore grids from our testing

A quick grep for "eul" in your modified code showed:

• some remnants of eul in tools/nudging.
• bld/scripts/remapfv2eul.ncl which say it maps from fv2 to eul. Is this script still relevant?
• bld/namelist/namelist_defintion.xml has eulc in a number of places. I'm not sure it that is still relevant or not.

There were plenty of other places in the CAM code where "eulerian" is still used, but I think they don't relate to the dycore EUL

I didn't touch the code in tools/nudging because it's not part of the EUL dycore, and more importantly, I don't have a way to test whether or not I broke it. But I'll go ahead and remove the Eulerian option if you think that's best.

I've removed bld/scripts/remapfv2eul.ncl.

The eulc references in namelist_definition.xml are related to vertical advection in SCAM. I think that use is independent of the EUL dycore. @jtruesdal, could you comment?

@patcal - Can you advise us on whether or not the eul option should be removed from the tools/nudging code, since this PR is removing the Eulerian dycore completely from CAM?

[jtruesdal]

@brian-eaton I would like to keep the eulc namelist definitions for SCAM as we hope to provide a simple eularian vertical transport for the single column model that is not associated with the current eul dycore.

@cacraigucar, I've removed the references to the EUL dycore from the nudging tools.

@brian-eaton thanks for adding the test grid issue here. I noticed that even though you have a single line for each issue at the top, it didn't add them to the development, which means they won't auto close. So I did that by hand for the bottom two, and the top one didn't show up in my simple search. If you figure you why they didn't get added to development let me know.

@jtruesdal - I believe we still need your reply to this question?

[jtruesdal]

@cacraigucar I did answer above saying I would like to keep the namelist options related to SCAM which refer to a generic eulerian vertical advection not the eul dycore.

@jtruesdal - Thanks - sorry I missed that!

Thanks for making the requested mods.
